This 2x6 USB 3 audio interface allows you to record with near-zero latency through the full range of UAD Powered Plug-Ins - ingeniously merging classic analog tones with cutting-edge features.

Record and Mix with Stunning 24-bit/192 kHz Sound Quality
With the highest dynamic range and lowest noise of any desktop interface, Apollo Twin USB gives you stellar 24-bit/192 kHz sound and breathtaking clarity.

Its premium mic preamps and class-leading conversion translate into rich three-dimensional recordings with exceptional depth and punch. Digitally controlled analog monitor outputs provide full resolution audio at all listening levels - letting you create better mixes in real-world environments.

A Complete Analog Studio with Realtime UAD Plug-In Processing
magine having access to a classic analog recording studio, right on your desktop. Apollo Twin USB lets you record and mix through the full range of UAD Powered Plug-Ins - including vintage EQs, compressors, reverbs, tape machines and more - at near-zero latency, regardless of your audio software buffer size.

Track Through Classic Preamps Using Unison? Technology
Unison technology allows Apollo'sTwin USB's mic preamps and front-panel DI to sound and behave like the world's most sought-after tube and solid state preamps, guitar amps, and stompboxes - including their all-important impedance, gain stage "sweet spots," and circuit behaviors. Based on breakthrough integration between Apollo's analog inputs and its onboard UAD processing, Unison lets you track through a range of colorful emulations from Neve, API, and Marshall with amazing tone.

Professional I/O Connections
Apollo Twin USB is a 2x6 interface with two class-leading mic/line preamps, two analog line outputs, two digitally controlled analog monitor outputs, and up to eight additional channels of digital inputs via Optical connection. Its conveniently located Hi-Z instrument input and headphone jack allow you to capture inspiration the moment it strikes.

Easy to Use with Any DAW
Apollo Twin USB is compatible with major DAWs, including Pro Tools, Cubase, Ableton Live, and more - allowing seamless integration no matter what recording software you use.

The key to its analog magic is onboard UAD-2 DUO DSP Processing, which powers the UAD plug-ins while reducing the strain on your host CPU. To get you started, Apollo Twin USB includes the "Realtime Analog Classics" plug-in bundle.
